Structure for 'dvc ' atom in sample description ('stsd')



Hope I'm not missing the obvious...

I've searched, with every keyword I can think of, for info on 
this in both lists.apple.com and 
developer.apple.com/documentation/. I have only been able to 
learn that its symbolic name is kDVCNTSCCodecType, but I have 
not found any description of the atom content. 

In the example .mov file I've decoded, that atom is 174 bytes in 
size. In theory it should (like other atoms in an 'stsd' 
container) contain whatever the codec needs to know in order to 
decode the corresponding 'mdat' data. I'm at a loss though to 
imagine that a dv codec needs quite that big a description...

Does anyone know, or know where I should look?

I've tried the QuickTime File Format doc (QTFF.pdf), but the 
latest copy I've found is dated 2001-03-01 and does not include 
this atom. Is there a newer version of this doc available, say 
in the "August 2005 ADC Reference Library Update" or "August 
Developer Documentation in PDF" downloads? Or is there one 
available under a license agreement or NDA?
